The first half of the
book is devoted to explaining the "whys" behind paleo. The final chapters
cover how to eat paleo and contain sample meals. At times, I wasn't a fan
of his tone but maybe I wasn't the target audience. Also in some chapters
his explanations were mostly anecdotes instead of scientific explanations
and often the meat of the argument was left out and simply references in the
sources. However, the chapter on grains was eye-opening and I had not heard
any of this information elsewhere.

If you don't pick up the book, it's still
worthwhile searching for more information about how grains are digested and
their negative impact on your body. Here is an
excerpt from the book.
